■
Hoses and connections should be
checked periodically for fit, wear and
damage and replaced or tightened, as
needed.
■
All cords and hoses should be located
away from walkways and aisles.
■ During certain operations, such as
high-temperature soak or when the
chamber is opened after firing, high
temperature convection currents are
created.
■ Do not touch the surface of the heat-
ing chamber, the heating elements or
the interior surface of the heating
chamber. These surfaces may cause
severe burns.
■ Always keep the chamber closed with
the lift in the up position between pro-
cesses or when the unit is not in use.
■
If the furnace is under vacuum in the
“Off” state for an extended period of
time, the O-ring of the lift plate may
adhere slightly.
■ Clean the furnace with a dry or slight-
ly damp cloth. Do not use any sol-
vents. Always disconnect power befo-
re cleaning.
0. Introduction
■
Be sure that the furnace is properly
installed per our instructions and that
the selected electrical outlet is prop-
erly grounded.
■
The electrical service provided must
be a dedicated line of the proper size
according to local electrical codes. Con-
sult a qualified electrician to ensure
that your amperage is sufficient to
prevent burdening of any existing circuit.
■ Do not use an extension cord with
the furnace. Check with your utility
provider for electrical codes, which
apply in your area.
■
In case of undervoltage, the tempera-
ture increase may be delayed.
■ Compressed air systems must meet
the listed requirements for use with
the unit. Connections should be made
by qualified personnel and all fittings
attached and used in accordance with
manufacturer’s instructions.
■
When heating the firing chamber, there
may be vibration noises from the
heating elements, this is normal.
■ In the case of faults or damages that
prevent safe operation, the equipment
should not be used, until the problem
is resolved or repaired.
■
Turn off the furnace, disconnect the
power cord and wait for the furnace
to cool to room temperature before
performing any recommended and
authorized routine maintenance or
service, due to the risk of electrical
shock, personal injury or death.
■
Do not attempt to repair, replace or
open any part of your furnace, unless
you have read the manual and the
repair or replacement is specifically
recommended therein. Any unautho-
rized attempt to repair, replace or
open any part of your furnace could
present a safety hazard and void your
warranty. All other servicing, either in-
warranty or out-of-warranty, should be
referred to our Customer Care Center.
